What Is Multi-Timbre - Yamaha PortaSound PSS-795 Owner's Manual

Note: If a certain MIDI instrument can receive MIDI
performance information on Multiple Channels and play out
several parts' sounds at a time, this MIDI instrument has
Multi-Timbre mode. And so the PSS-795 does.
f. What is Multi-Timbre?
Here we will give the little explanation about the Multi-
Timbre. As the illustration on the previous page "e.
Matching MIDI Channels", if you have a Master device
which can control multiple Slave instruments on respective
Channels (ex. Sequencer) and several Slave instruments,
you will have them make an automatic ensemble and will
be a MIDI beneficiary. However, imagine if you wish to
reproduce a philharmonic orchestration, besides a solo,
combo, or quartet.... Simply talking, it will be required as
many Slave instruments as the parts or members in the
orchestra. This is no easy way of musical enjoyment.
Generally, Multi-Timbre is an easy and economical way to
carry out multiple MIDI performances simultaneously. In this
case, a single Multi-Timbral Sound module will accept the
MIDI messages on multiple Channels and reproduce the
multiple performances. The Sound Module of your
PortaSound is provided with this function. The following
diagram will help you understand the Multi-Timbre:

OUTPUT
As shown in the above diagram, the PortaSound has 16
Channel Buses toward its Sound Module, and they
correspond to MIDI Channels 1 to 16 respectively (16
vertical arrows in the center of the diagram).
Built-in controllers such as Keyboard, 8 Pads, Vector
Synthesizer, Song Memory, and Auto Accompaniment are
designed to drive the Sound Module with their respective
34
comprised of
Root and Chord
MIDI Informations and functions. MIDI IN Terminal is a
gateway of MIDI Information from an external Master
controller. These are illustrated by 6 arrow groups toward
Channel Buses. That is, you can play with a single Voice
on the whole Keyboard (drive the Sound Module to sound a
single Voice) on a KEYBOARD TRANSMIT CHannel(*1)
selected (See page 36 for details.). If you activate the
Vector Synthesizer, you can play with 4 Voices at a time
(drive the Sound Module to sound 4 Voices) on Channel 1
to 4. Or, if you activate the Auto Accompaniment, the
whole Keyboard will be split into two sections (C1-F#2: for
accompaniment, G2-Ce: for melody) and Auto
Accompaniment will drive the Sound Module to sound
several Voices on Channel 10 to 16. In the same way, 8
Pads will drive the Sound Module on Channel 16. Song
Memory("2) is a little complex as it enables Multi-Track
Recording and functions in combination with other
controllers, but finally it will drive the Sound Module fully on
Channel 1 to 16. And, you can drive the Sound Module
also from an external Master controller via MIDI IN
Terminal. In this case, you can drive the Sound Module ^
the MIDI Information on the Channel(s) specified in
RECEIVE CHannel selection (See page 35 for details.).
(*1) KEYBOARD TRANSMIT CHannel will be selected by a couple of link
Switches as shown in the diagram.
(*2) Song Memory is a little complex as it enables Multi-Track Recording
and functions in combination with other controllers. That is, for
example, in case of recording on one of the MELODY Tracks 1 to 5,
KEYBOARD TRANSMIT CHannel will be automatically switched to the
corresponding Channel to the Track (Channel 5 to 9). Or, in case of
recording on VECTOR SYNTH Track, the VECTOR SYNTH ON/OFF
Switch will be automatically turned on and switched to Transmit
Channel 1 to 4 (dedicated to Vector Synthesizer). Or, in case of
recording on PAD Track, the Transmit Channel will be automatically
Switched to Channel 16 (dedicated to 8 Pads). Or, in case of recording
on AUTO ACCOMP. Track, the Fingering will be automatically selected
(initially FINGERED) and switched to Transmit Channel 10 to 16
(dedicated to Auto Accompaniment).

Multi-Timbre on the PortaSound will be performed with Dynamic Voice
Allocaiton. (See page 37 for details.)

When recording on one of the MELODY Tracks 1-5 by the keyboard Т
KEYBOARD TRANSMIT CHannel will be automatically switched to te
corresponding Channel.
